Kubernetes Services provide a great way for containers to communicate. In this lab, you will practice your knowledge of Kubernetes Services by selecting and implementing the appropriate Service types to fulfill specific use cases.
Learning Objectives
Successfully complete this lab by achieving the following learning objectives:
- Publish an Application Internally within the Cluster Network
There is a deployment called
desert-terrapinin thedefaultNamespace that needs to be exposed within the cluster network. The relevant Pods listen on port80and have the labelapp=desert-terrapin. Expose the Service on port80as well.Create the appropriate Service with the name
desert-terrapin-svc.- Use a Service to Publish an Application Externally
The
sea-turtledeployment in thedefaultNamespace needs to be exposed to users outside the cluster.The application’s Pods listen on port
80and all have the labelapp=sea-turtle. Use port30080on all of the cluster nodes to make the Service available outside the cluster. (Hint: You can specify the external port using thenodePortfield.)Create the appropriate Service with the name
sea-turtle-svc.
